1.2 About the Device
The Honeywell Base Radio is a reliable Radio Frequency (RF) transceiver with a variety
of available outputs contained in an explosion proof housing useable in many hazardous
and hard-to-reach areas. The time and expense of running wires often makes it difficult to
measure parameters that have an economic impact on your plant operation, but the Base
Radio allows you to quickly and accurately monitor those devices at a fraction of the cost,
giving you bigger and faster returns on your instrumentation investments.
The Base Radio communicates in a secure, frequency digital protocol over a band of
frequencies from 902 MHz to 928 MHz. These devices do not require permits or licenses
and are easily setup and installed right out of the box.

The Base Radio RF settings should be configured as follows:
•
•
•
Set the RF Channel to any available RF CHAN that matches the one used by
the Transmitters you wish to communicate with (other than RF OFF).
Set the Baud Rate to 76.8 K or to the Baud Rate used by the Transmitters
with which you wish to communicate.
HI RF ID = the highest transmitter RF ID you assign to this network.
6.
7.
Configure the Modbus settings
Verify “COMM OK” message on Base Radio LCD screen
If you are not receiving a “COMM OK” message on the Base Radio check the
following:
•
•
•
Is the Base Radio set to the above listed configurations?
Are all the Transmitters on?
Are the Transmitters set to the matching RF configurations (see Section 5 of
Transmitter and Base Radio User Manuals)?
•
Are the Base Radio and Transmitters unable to communicate due to obstructions or
distance (see Transmitter Manual: Transmitter Placement section)?
Warning! If the Transmitters have been running for an extended period of
time with no signal from the Base Radio (the Base Radio is off or not
present), the Transmitters will only search for the Base Radio every one
hour or so. Turning the Transmitters off and back on will cause them to
begin searching immediately.

3 Installation
This section discusses both the mechanical and electrical aspects of installation. It is
divided into the following sections:
3.1 Mechanical Installation
In this section, the mechanical installation instructions are discussed for the various setup
capabilities of the Base Radio. The subsections are as follows:
The Honeywell Base Radio is a rugged device, which provides optimal performance
when installed with careful consideration. Installation practices greatly affect the life that
you can expect from your Honeywell Base Radio. The main considerations for installation
are covered below.
Give careful consideration to the environment where you will be installing the devices.
Avoid installations that expose the device to excess temperature, high vibration,
considerable shock, or exposure to dripping condensate or corrosive materials. Also
avoid installing the device in an unserviceable location.
Most often these problems can be avoided with some thought at the time of installation.
The practices noted below are generally recommended, but they can only act as
guidelines and cannot cover all possible variations.
The final installation must be made at the discretion and approval of the user. You must
be the judge of the actual installation.
Warning! During installation do not apply force to the instrument housing
or antenna. Use a proper wrench for all installations. Failure to use correct
installation procedures can cause damage to the Base Radio.
3.1.1 Base Radio Positioning
Correct positioning of the Base Radio will ensure the best performance of the device.
Because the Base Radio is the central communication device of all Transmitters that are
assigned to it, the Base Radio should be located in an area that is somewhat central to all
of the Transmitters.
determined by a number of factors, including the Baud Rate Setting. When planning the
positioning of the Base Radio, try to place the Base Radio in a location with an
unobstructed view to the most Transmitters possible.

Figure 3-1 General Layout
Remember, the approximate line of sight range between a Transmitter and Base Radio is
determined by the Baud Rate as listed below:
•
•
•
76.8K -76.8 Kbaud, Range of 500 to 750 ft
19.2K - 19.2 Kbaud, Range of 2,000 to 2,500 ft
4.8K - 4.8 Kbaud, Range of 3,000 ft
Note This range is reduced by the amount of RF Noise present, obstructions, and the
material properties of those obstructions.
Only place the Base Radio in ambient operating temperatures of -40°F to 185°F (-40°C to
85°C).
Make sure you have power and communication to the Base Radio available (see 3.2
Because there are so many setup possibilities we cannot cover them all. A correct setup
would make sure that the above warnings are heeded and that the Transmitter and Base
Radio are capable of communication. The RF Placement Procedure section of the
Transmitter Guide will help you to determine if you have a selected the correct installation
points and orientations for your application.

Warning! Explosions may result in death or serious injury. Do not remove
the instrument cover in explosive atmospheres when power and/or
communications are on.
To begin the electrical installation first remove the explosion proof housing cover from the
Base Radio, if you have not already done so. Point the Base Radio antenna away from
you and look at the green PC Board found directly underneath the NEXT and ENTER
buttons. You should see two terminal blocks and some labels as shown in Figure 3-3.
Figure 3-3 Terminal Block Labels

Download from Www.Somanuals.com. All Manuals Search And Download.
Once you have located these terminal blocks you can wire the Base Radio accordingly.
The best way to wire the Base Radio is to:
•
•
•
•
Remove both terminal blocks from the jacks on the Base Radio
Insert the wire through the conduit hole on the bottom right of the Base Radio
Secure the wire into the proper terminal blocks
Then plug the terminal blocks back into the proper jacks on the Base Radio.
Warning! If the Transmitters have been running for an extended period of
time with no signal from the Base Radio (the Base Radio is off or not
present), the Transmitters will only search for the Base Radio every one
hour or so. Turning the Transmitters off and back on will cause them to
begin searching immediately.
3.2.2 Wiring Power to the Base Radio
The Honeywell Base Radio is designed to use a 24 VDC power supply at a minimum of
0.5 Amps. Honeywell offers a DIN rail mountable 100-240VAC 50/60Hz to 24VDC
transformer for this purpose, AIC #. For more information, contact your Honeywell
Representative.
The Common or Negative wire should be placed in the left most slot labeled “GND” on
the PC Board of the terminal block in Figure 3-4. The Positive wire should be placed in
the same terminal block in the slot labeled “24V” on the PC Board as shown in Figure

software may require the use of an RS-485 to RS-232 converter, as most PCs cannot be
wired directly to RS-485.
To wire the RS-485 cable to the Base Radio we recommend using a 22AWG twisted pair
shielded wire. Place one of the twisted pair wires in the “A” (Tx+/Rx+) slot of the same
terminal block as the power supply wires, and the other wire in the “B” (Tx-/RX-) slot of
the terminal block as shown below in Figure 3-5.
Figure 3-5 Wiring RS-485 to the Base Radio
RS-485 may be wired in-line (in series) to multiple Base Radios. This is called “daisy-
chaining”. Only Base Radios using Modbus RS-485 output can be daisy-chained. See
Section 3.2.6. Note that Base Radios daisy-chained must be set to different RF Channels
to communicate properly on the same wire.
3.2.4 Wiring the RS-485/232 Converter to the Base Radio
Honeywell offers an optically isolated, surge protected, DIN Rail mountable RS-485/232
converter, AIC #. Because there are many RS-485/232 Converters available, please see
your converter’s instruction manual for details as this section will only discuss the wiring
of the B&B 485LDRC9 converter.
The Base Radio communicates via a RS-485 half-duplex differential signal with A being
Tx+/Rx+ and B being Tx-/Rx-. To properly wire the Base Radio to the 485LDRC9, you
should follow Figure 3-6.

To configure the 485LDRC9 to the appropriate baud rate (38.4Kbaud), a set of dip
switches must be configured. These switches can be found on the side of the converter.
The first four switches should be in the ON position to indicate that the communications
are half-duplex. The fifth switch should also be in the OFF position as this activates the
120 Ohm termination resistor within the converter. This terminator is only useful for long
RS-485 buses, or other calculated circumstances. Finally, switches six, seven, and eight
should be set to the OFF position to indicate the correct baud rate. (Note: An 8.2 K
resistor (R11) has been installed at the factory to achieve these higher baud rates. If you
did not purchase the converter from the factory, you will need to install the resistor.)
To wire power to the 485LDRC9, place a +10 to 30 VDC supply to terminal F, and place
the ground (V-) to terminal C.
The final step in installing the converter is to attach a DB-9 RS-232 (serial) cable from the
converter to an available serial port on your computer.
Note The RS-485 bus is half-duplex. If the Base Radio in the application is wired to a RS-
485 to RS-232 converter, the A (Tx+/Rx+) and B (Tx-/Rx-) wires may need to be crossed
for correct operation. Please see the converter’s manual for further instructions.
3.2.5 Wiring the RS-485/USB Converter to the Base Radio
Note The RS-485 cable should NOT be connected to the RS-485/USB converter before
the converter drivers have been installed.
Honeywell also offers a non-optically isolated RS-485 to USB converter. The USB
Converter provides easy connectivity between the PC and standard communication
ports, not requiring PC reconfiguration, assignment of IRQs, or jumper settings.
Use of this device requires a PC with a USB port compliant with USB 1.1 or later.
The RS-485 to USB converter is equipped with a USB cable and a USB type A connector
for connection to a PC USB port and a male DB-9 for connection to an RS-485 equipped
data or communication terminal.

“USB to Serial Adapter”. You need this number to set the WMT’s RF Server to
look at the correct COM PORT for incoming information.
To specify this COM PORT, start the RF Server and Right-Click on the RF
Server Icon (see the WMT User’s Guide, Section 4 for more details). Select
Options. Then click ADD to add the converter’s COM PORT. The baud rate
should remain at 38400. Then select OK and the added port will be displayed.
Select OK.

3.2.6 Daisy-Chaining Multiple Base Radios to Single RS-485/Power
Two or more Base Radios may be placed on a single RS-485 communication line, and a
single power supply line (provided the power supply and wiring can handle the load). This
section will provide the information needed to daisy-chain multiple Base Radios.
However, be sure to complete Section 3.2.8 on correct Base Radio termination if doing
so.

3.2.6.1 Daisy-Chaining Power to Multiple Base Radios
A consideration when daisy-chaining power to multiple Base Radios is the power draw at
power supply. Each Base Radio will typically draw 200mA @ 24VDC. This means a
single Base Radio will draw a typical average power of 4.2W.
If using the supplied DIN rail mounted 15W power, it is suggested that no more than
three Base Radios be tied parallel to this supply.
To daisy-chain two or more Base Radios together, each Base Radio should be wired in
parallel to the next while making sure power is not supplied from two separate supplies to

3.2.6.2 Daisy-Chaining RS-485 to Multiple Base Radios
Modbus connections can be daisy-chained together, but WMT connections cannot. There
can only be one Base Radio, multiple Output Modules, and a PC on the same WMT RS-
485. If you have two Base Radios connected to a PC running WMT, you must have two
COM ports.

3.2.7 Terminating Communications Wiring to the Base Radio
RS-485 is capable of maintaining communications over a maximum distance of 4000
feet. In most (and we recommend all) situations the unit that comprises an “end” of an
RS-485 network should be terminated by a resistor wired across the A and B wires.
In the case of a daisy-chained application the end unit should be terminated. The end unit
is the unit that is located at the end of the series of units. In a PC to Base Radio only
application, the end unit is the Base Radio. Note: a PC is also an end unit, but the
termination for this end unit is done within the converter. In a multiple unit daisy-chain
Figure 3-9 Example of End Unit in Daisy-Chain Configuration
Termination of an end unit is done by placing a resistor across the A and B wires of the
RS-485 cable. The value of this resistor should match the characteristic impedance (Zo)
of the RS-485 cable. The characteristic impedance (Zo) is published by the manufacturer
of the RS-485 cable you are using. If you are using the Belden RS-485 wire
14
Download from Www.Somanuals.com. All Manuals Search And Download.
(recommended in section 3.2.1) the value of the resistor should be a 120 Ohm ¼ watt
resistor.
To terminate a Base Radio, place one end of the resistor in the open terminal block’s B
slot and place the other end of the resistor in the open terminal block’s A slot. Doing so
will place the resistor across the A and B wires, as needed. An example of this is shown
Figure 3-10 Example of Correct Termination Resistor Setup
3.2.8 Grounding the Base Radio
In order to assure safety requirements on your Base Radio, the Base Radio housing must
be grounded. We have provided a grounding screw located on the left side of the Base
Radio housing. To ground the Base Radio simply place a wire from the grounding screw
to a grounded object.
Possible grounded objects include:
•
•
•
The building’s metal frame-work
Any electrical conduit
A suitable grounding or lightning rod
3.2.9 High Gain Antenna
A high-gain antenna is available for the Base Radio. This antenna generally doubles the
signal range of the Base Radio, but requires an installation in a general-purpose area.

5 Configuring the RF Communications
In order for the Base Radio and the Transmitter to communicate they must be on the
same RF Channel, and must be transmitting at the same Baud Rate. All Transmitters and
Base Radios are set to RF OFF default configurations at the factory, and must be field
configured for proper operation. The subsections are as follows:
Warning! If the Transmitters have been running for an extended period of
time with no signal from the Base Radio (the Base Radio is off or not
present), the Transmitters will only search for the Base Radio every one
hour or so. Turning the Transmitters off and back on will cause them to
begin searching immediately.
5.1 RF Channel Selection
All Base Radios and Transmitters can be set to one of 16 different communication
channels. The only Transmitters recognized by a particular Base Radio are the units that
share the same RF Channel as that Base Radio. This allows the user to decide which
Transmitters communicate with each Base Radio.
Each Base Radio comes from the factory set to the RF OFF channel. This means the
Base Radio will not communicate with any Transmitters. To set the Base Radio for
communication, first determine the channel that you wish to use. To determine which RF
Channel to use, you should know if there are any other Base Radios in the same vicinity
and then choose a different channel number. After deciding on the RF channel number,
Channel.
Figure 5-1 Menu Map to RF Channel Setting
Once you are in the RF Channel menu, you can increment it by pressing the NEXT
button. When selecting the RF Channel, do not choose an RF Channel that is currently
being used by other Honeywell Wireless Systems as this can cause communication
problems.

5.2 RF Baud Rate Selection
The RF Baud Rate refers to the speed at which the Base Radio and Transmitters
communicate. There are three selectable settings with the quickest update times and
longest communication ranges listed below:
•
•
•
4.8K — Rate of 4.8 Kbaud (Update every 20 seconds)
— Range of 3000 ft (Line of Sight)
19.2K — Rate of 19.2 Kbaud (Update every 5 seconds)
— Range of 2000 ft to 2500 ft (Line of Sight)
76.8K — Rate of 76.8 Kbaud (Update every 1 second)
— Range of 500 ft to 750 ft (Line of Sight)
A faster RF Baud Rate will allow you to transmit more information in a certain period of
time, but it will also limit your range. If you need more distance out of your Transmitters or
are encountering difficulties by frequently losing communications, then select a slower
baud rate or switch to a high gain antenna.
Note If you change the baud rate of the Base Radio, you must also change the baud rate
of all other Transmitters that are communicating with that Base Radio.
Follow the Base Radio menu map shown in Figure 5-2 to configure the RF Baud Rate.
The factory default is the 19.2K Baud Rate.

5.3 High RF ID Setting
The Base Radio uses this parameter along with the RF CHAN and BAUD RT parameters
to set up communication with Transmitters. This setting should be a number between 1
and 100 corresponding to the Transmitter with the highest RFID on the system. Any
Transmitter with an RFID set above the HI RFID setting will not communicate with the
Base Radio. The factory default is 001.
Figure 5-3 High RFID Setting
Note that the Output Modules with firmware prior to 1.7 (purchased before May 2006) will
not work with the Base Radio when the HI RFID setting is set above 50.

Communications
The subsections are as follows:

6.3.1.1.1: Base Radio Device Type Holding Registers
6.3.1.1.2: Base Radio Device Status Holding Registers
6.3.1.1.3: Base Radio On/Offline Transmitter Registers
6.3.1.2: Transmitter Holding Registers
6.3.1.2.1: Transmitter Device Type Holding Registers
6.3.1.2.2: Transmitter Device Status Holding Registers
Note This device supports Modbus RTU (Binary) communications. Note that the ASC-II
transmission mode is not supported.
6.1 Base Radio Setup
The purpose of this section is to guide you through the configuration of the Base Radio in
order to enable communications with your particular Modbus Protocol.
6.1.1 Modbus Baud Rate Setting
In order for the Base Radio to communicate with other devices, such as the server
computer or an existing PLC/DCS system, they must share the same Modbus Baud
Rate.
To set the Modbus Baud Rate, first determine which rate your system requires. If your
system will allow any baud rate, we suggest you use the fastest setting; however, some
systems cannot handle these faster baud rates due to external noise and transmission

distance. If you encounter communication problems between the Base Radio and server
computer or existing system, try a slower baud rate setting.
Once you have determined the Modbus Baud Rate you wish to use, follow the Base
Radio menu map shown in Figure 6-1 to configure the Baud Rate. The factory default is
19.2 K.
Figure 6-1 Menu Map to Modbus Baud Rate Setting
6.1.2 Modbus Device ID Setting
The Modbus Device ID allows a PLC or DCS to find the proper Base Radio on a RS-485
Network.
Because Modus needs a device ID for each Transmitter, they have been virtually
mapped according to the Base Radio with which they are communicating. The device ID
range is dependent on the MODMAP setting in the Base Radio. (See Modbus Mapping
In the Register Mapping Mode you may select any device ID from 1 to 247. This number
will be the device Modbus device ID at which all the readable registers for the Base
Radio and every Transmitter will be located. More detail about each register, and its
meaning can be found in the Modbus Communications Protocol section.
In the Device ID Mapping Mode you may select any device ID from 1 to 247 minus the
number of Transmitters communicating with this Base Radio. The change in the device
ID ceiling is due to the fact that each Transmitter’s device ID is located at its RF ID + the
Base Radio device ID. Thus you need the space beyond the Base Radio address to
contain all of the Transmitters’ addresses.
For example: If there are two Base Radios on the Modbus RS-485 network, and each of
the two Base Radios are communicating with three Transmitters, the device ID scheme
would result as follows:
23

•
•
Base Radio with Modbus device ID 001
⇒ Transmitter with RF ID 1 is found at Modbus device ID 002
⇒ Transmitter with RF ID 2 is found at Modbus device ID 003
⇒ Transmitter with RF ID 3 is found at Modbus device ID 004
Base Radio with Modbus device ID 101
⇒ Transmitter with RF ID 1 is found at Modbus device ID 102
⇒ Transmitter with RF ID 2 is found at Modbus device ID 103
⇒ Transmitter with RF ID 3 is found at Modbus device ID 104
More detail about the registers at each address, and their meaning, can be found in the
Modbus Communications Protocol section.
Once you have determined the Modbus Device ID you wish to use, follow the Base Radio
menu map shown in Figure 6-2 to configure the device ID. The factory default is 001:
Figure 6-2 Menu Map to Modbus Device ID Setting
Note The Base Radio provides different Device ID modes in order to support a wide
range of Modbus equipment.
In the Register Mapping Mode the data for the Base Radio and all Transmitters are
located under a single device ID. This ID may be any allowable Modbus address between
1 and 247 that doesn’t conflict with an address of existing device or Modbus network.
In the Device ID Mapping Mode each Transmitter is given its own unique ID and
registers. The Transmitter ID is equal to the value of the Base Radio ID added to the
Transmitters RF ID.
Note Make sure that the HI RF ID setting has been configured properly or the Modbus
addressing scheme could be affected.
To properly set the HI RF ID setting see Section 4.2.

6.1.3 Modbus Parity Setting
The Modbus Parity distinguishes which type of parity is used to validate each packet of
information on the RS-485 Network. The type of parity required is usually indicated by the
user’s PLC.
Selecting EVEN or ODD parity will automatically include one STOP bit per frame.
Selecting a parity of NONE will automatically include two STOP bits as per the Modbus
communications specification.
default is EVEN parity.
Figure 6-3 Menu Map to Modbus Parity Setting
6.1.4 Modbus Mapping Mode Setting
The Modbus Mapping mode distinguishes which type of mapping mode is used to map
the Modbus registers according to the device IDs.
Note Make sure that the HI RF ID setting has been configured properly or the Modbus
addressing scheme could be affected. To properly set the HI RF ID setting see Section
There are two possible mapping modes that can be used. The first is the Device ID
mapping mode. Using this mode gives the Base Radio a device ID equal to its device ID
setting. There are then 10 Modbus registers located at this device ID for this Base Radio.
Each Transmitter communicating with this Base Radio is then located at device ID X,
where X is the RF ID of the Transmitter + the Device ID of the Base Radio. There are 10
Modbus registers for each Transmitter located at that Unit’s device ID. For more
information on the registers, see Section 6.2: Modbus Communications Protocol.
The other possible mapping mode that can be used is the Register Mapping mode. Using
this mode gives the Base Radio a device ID equal to its device ID setting. Then, the 10
Base Radio Modbus registers are registers 1 – 10, and the Transmitter with RF ID 1 is
located at the SAME device ID as the Base Radio but its registers are registers 11-20.
Each subsequent Transmitter is mapped similarly. For more information on the registers,
Section 6.2: Modbus Communications Protocol.

The factory default is the Device ID mode.
Figure 6-4 Menu Map to Modbus Mapping Mode Setting
6.2 Modbus Communication Protocol
The Base Radio connects to the Host (Master) system using Modbus over a serial RS-
485 line. The Base Radio supports Modbus RTU transmission mode at baud rates of
9600, 19200, 38400, 57600, or 115200 baud with even, odd, or no parity and 8 data bits.
One stop bit is used if even or odd parity is selected and two stop bits are used if the no
parity option is selected to fill out the character frame to a full 11-bit character. Unless
modified by the user, default values of 19200 baud, 8 data bits, even parity, and one stop
bit are used.
Note This device supports Modbus RTU (Binary) communications. Note that the ASC-II
transmission mode is not supported.
The Base Radio is always located at the device ID selected by the DEV ID menu item.
Transmitters can be configured either to be assigned to an individual Modbus device ID
or to holding registers within the Base Radio device ID through the appropriate selection
in the MODMAP menu item. There are two MODMAP modes available: DEVMODE and
REGMODE.
If the device ID mode (DEVMODE) is selected, a Transmitter's data may be accessed
with the Modbus Read Holding Register Command (03) by using the Transmitter's
equivalent Modbus device ID. The Transmitter's equivalent Modbus device ID is the Base
Radio's device ID + the Transmitter's RF ID. For example, if the Base Radio’s device ID
was 10 and a Transmitter’s RF ID was 5, the Transmitter would be accessed under
Modbus device ID 15. Using the device ID mapping mode adjusts the upper limit of the
Base Radio’s device ID to 247 minus the number of Transmitters on the RF network. For
example, if 5 Transmitters were on the Base Radio’s network, the maximum Modbus
device ID would be 242.
If the register-mapping mode (REGMODE) is selected, a Transmitter’s data may be
accessed with the Modbus Read Holding Register command (03) using the Base Radio’s
26

device ID. The Base Radio uses register addresses 1 through 10 with each subsequent
group of 10 registers used by a Transmitter.
The RF online/offline status of a Transmitter can be determined through a number of
different sources. In the Base Radio holding registers, a count of the current number of
online Transmitters can be found at address 00004. Also the individual online/offline
status of each Transmitter is stored in the Base Radio holding registers at addresses
00005, 00006, 00007, and 00008. These registers are bit field variables with each bit of
the 16-bit number representing the status of a Transmitter. If the bit is set, the
corresponding Transmitter is online. If the bit is cleared, the corresponding Transmitter is
offline.
In the Transmitter holding registers, bit 1 in the Transmitter & Sensor Status holding
register holds the online/offline status of the particular device. Any Transmitter that is
currently offline will return NaN (Not a Number) when queried for its primary or secondary
measurement value. Note that if a Transmitter is online and is a single measurement
device type, NaN will also be returned for the Secondary Sensor Value, as the
measurement does not exist in these devices.
6.3 Modbus Commands
The Base Radio responds to six Modbus commands including the Read Holding
Registers (03), Diagnostic (08), Get Com Event Count (11), Get Com Event Log (12),
Report Slave ID (17), and Read Device Identification (43). The Read Holding Registers
command provides the bulk of the functionality with the remaining commands being used
for diagnostics/troubleshooting purposes. No other Modbus commands are supported
and will be responded to with an ILLEGAL FUNCTION exception (code 01). A description
of each command code is listed in the following sections.
6.3.1 Command 03-Read Holding Registers
This command is used to read the contents of a contiguous block of holding registers in a
Base Radio or Transmitter. If an invalid register address is requested, an ILLEGAL DATA
ADDRESS exception (code 02) will be returned.
Section 6.4 lists the holding registers for the Base Radio and Transmitters, as well as
how to understand the contents of the registers.
6.3.2 Command 08- Diagnostic

device ID mapping mode (See Section 6.2).
6.3.3 Command 11- Get Com Event Counter
This command returns a two-byte status word and the device’s event counter. The status
word will either be 0 or 65535 if the previous command is still being processed. The event
counter is incremented for each successful message received. The counter is not
incremented for commands that return exception responses or commands that fetch
event counters. The event counter will eventually roll over to 0 after reaching a count of
65535. Note that identical information is returned for any device ID that the Base Radio
has control of (i.e. including Transmitters mapped to virtual device IDs when operating in
the device ID mapping mode).
For further details on this command, please consult the Modbus protocol specification.
6.3.4 Command 12- Get Com Event Log
This command returns a status word, communications event counter, message count,
and a field of bytes from the communications event log. The status word and
communications event counter are identical to those returned by Command 11 (Get Com
Event Counter) above. The message count is a count of the total number of messages
received by this device, including messages intended specifically for this device as well
as other devices on the Modbus network. The event log keeps track of information on the
last 7 communications events. Note that identical information is returned for any device
ID that the Base Radio is controlling (including Transmitters mapped to virtual device IDs
when operating in the device ID mapping mode).
For further details on this command, please consult the Modbus protocol specification.
6.3.5 Command 17- Report Slave ID
This command returns the device type, device status, and a run indicator status byte. The
16-bit device type and device status words are identical to those held in the holding
registers. The run indicator status byte is 255 (0xFF hex) if the device is online and 0
(0x00 hex) if the device is offline. Unlike some of the other diagnostics commands,
different information is returned depending on whether the device ID used in this
command corresponds to the Base Radio or one of the Transmitters mapped to a device
ID when operating in the device ID mapping mode.
For further details on this command, please consult the Modbus protocol specification.

6.3.6 Command 43- Read Device ID
This command returns identification information relating to the device. The conformity
level of this command is level 01, basic identification (stream access only). As with most
of the other diagnostic commands, identical information is returned for any device ID that
the Base Radio is controlling (including Transmitters mapped to virtual device IDs when
operating in the device ID mapping mode).
For further details on this command, please consult the Modbus protocol specification.

total from the subtraction and subtract the next largest number possible and so on until
the result is zero. Each value that was used in the subtraction indicates that the
Transmitter is online.
For example: The On/Offline Status holding register contains the value 15. In this case
the largest value we can subtract is 8, which leaves a result of 7. Now we can subtract 4
from 7 and get 3. Now subtract 2 from 3 and we get 1. Finally we subtract 1 from 1 and
get 0, so we are done. Which Transmitters are online? We subtracted 8,4,2 and 1, and
these numbers correspond to Transmitters’ with RF IDs 1,2,3 and 4.
Note An alternate method to determining which Transmitter(s) are online is to look at the
Base Radio Holding Register as a binary number with the rightmost bit representing
Transmitter 1 and the leftmost bit representing Transmitter 16. For example, the binary
representation for Transmitters 1-4 online is as follows:
0000000000001111
In another example, say the On/Offline Status holding register contains the value 6. We
can subtract 4 to get 2. Then we can subtract 2 to get 0. Thus Transmitter 2 and 3 are
online, but Transmitters 1 and 4 are offline.

Again, like Section 6.4.3, the status can be resolved by subtracting the largest number
listed above from the value received from the holding register, and then subtracting the
next highest and so on until the result is 0. Each of the values used indicate the
respective condition listed above.
For example, the holding register reads 9, then subtract 8 and get 1. Then subtract 1
from 1 and get 0. Thus from the list above, we have a Sensor Error Condition and the
Transmitter is online.
6.6 Square Root Function
The Square Root Function only works with the Differential Pressure Transmitter. When
the DP Transmitter is in Orifice mode, a Square Root calculation is performed. You have
the option to display the Square Root Calculation. If this option is enabled, it will be
displayed as Percent Square Root in WMT and sent to a Modbus Register.
The Square Root Calculation must be enabled through WMT. To display the Square Root
Calculation, first open the Configuration dialog box for the DP Transmitter and select the
Operation Mode tab. Make sure you have selected Orifice Flow from the mode menu.
Then, from the Flow Units drop-down list, select Percent - Vol Flow. If the Density check
box is selected, then Percent - Mass Flow can also be selected from the Flow Units
drop-down list to show the Square Root Calculation.

Appendix A Navigating the Menus
Pressing either the NEXT or ENTER buttons located on the front of the Transmitter or
Base Radio just below the Liquid Crystal Display (LCD) screen is all that is needed to
navigate the respective menus. Pressing both of these buttons for one second will turn
the unit on.
Pressing the NEXT button at any time while the Base Radio is cycling through the normal
messages causes the Base Radio to enter the setup mode. The NEXT button is then
used to step through menu options, and the ENTER button is used to enter a submenu of
what is displayed on the LCD at that time. If no button is pressed within a 30 second
period the unit goes back to the normal display mode.
If you enter a submenu that requires a numerical input, such as 001, the leftmost 0 will be
blinking. This indicates that pressing the NEXT button will increment this value with each
press from 0 to 9 and back to 0 again. Pressing the ENTER button will move to the next
available value. If the last value is blinking, pressing ENTER will save the entered values
and return to the return from the sub menu.
